SPLICE FOR ELECTRIC WIRES.

Specification of Letters Patent.

Application filed November 18, 1905- Serial No. 287,937-

To (0Z7 whmn it may concern:

Be it known that I, CONRAD J. DORFF, a citizen of the United States ofAmerica, and a resident of Chicago, in the county of Cook and State ofIllinois, have invented certain new and useful Improvements in Splicesfor Electric Wires, of which the following is a specification. fig, Thisinvention relates to that type of splices for electric wires which areformed from a metal strip bent into shape to form two adjoining channelsfor the reception of the respective wire ends; and the presentimprovement has for its object to provide a simple and efficientstructural formation of parts whereby leakage of the spelter used tobraze the splice in shape into the interior of the channels ispreventedand with which the diameter of the said channels can be forciblydecreased and the circular nature thereof be still preserved, all aswill hereinafter more fully appear and be more particularly pointed outin the claims.

In the accompanying drawings, illustrative of the present invention,Figure 1 is an elevation of the splice in an untwisted conditionprevious to use. Fig. 2 is a similar view of the splice in its twistedcondition. Fig. 3 is an enlarged end view.

As represented in the drawings, the splice is of the same general formand construction as the ordinary form of wire splices now in general useand comprises a plate of ductile metal having its longitudinal sideportions bent around to form two adjoining circular channels 1 and 2 forthe reception of the respective ends of the wires to be spliced, the

central part of said plate having a longitudinal ridge 3 to assist inimparting the required circular form to the channels 1 and 2 aforesaid.

The present improvement involves the combination of the centrallongitudinal ridge 3, formed with counterpart flat faces at either sideof its apex, and a corresponding formation of the longitudinal platefrom which the splice is formed, so that said longitudinal edges willhave beveled surfaces I of considerable extent to abut upon theaforesaid straight faces of the longitudinal ridges 3 and by thisextended surface contact thus produced prevent any leakage into theinterior of the channels 1 and 2 of the spelter used in brazing thejoints, and at the same time such construction affords a true circularform in cross-section to said channels.

Having thus fully described my said invention, what I claim as new, anddesire to secure by Letters Patent, is

A wire-splice formed of a plate of ductile metal having a centrallongitudinal ridge, the surfaces on each side of the apex of which areflat, and beveled longitudinal edges, the respective side portions ofthe plate being bent in opposite directions toward each other to formadjoining channels and bring the beveled edges aforesaid into extendedsurface contact with the flat faces of said longitudinal ridge to afforda true circular form in cross-section to said channels.

Signed at Chicago, Illinois, this 14th day of November, 1905.
